> | Lab 1.5.13.1 Router lab setup review- Overview Estimated Time: 30 min. Objectives: Setup the Cisco lab equipment according to the semester 2 topology diagram shown above or analyze the physical connections of an existing lab setup. Document the cabling and connections between devices Draw a diagram of your lab equipment setup Background: This lab will serve as a refresher for how the Cisco lab routers are set up and connected for the Semester 2 topology (see diagram above). This is a review of the semester 2 network topology. You will setup and document the physical connections between these routers and the other lab hardware components such as hubs, switches and workstations. If it is not possible to start with the equipment disconnected, document an existing lab setup. This lab will utilize the standard setup consisting of 5 routers, 4 hubs, 1 switch and at least 5 workstations plus all associated cabling and adapters. It is a good idea to work on this lab and the next one (1.5.13.2) simultaneously if possible. The next lab will give you an opportunity to develop an IP addressing scheme based on multiple Class B subnet addresses. You may work in teams or 3 to 5 and while one group is configuring the router lab physical setup the other can be designing the class B addressing scheme on the board. Tools / Preparation: Prior to starting this lab you will need to have the equipment from the standard 5-router lab available (routers, hubs, Switch etc.). The routers and hubs should be disconnected and stacked. Each cabling type (WAN, LAN, console, power) should be grouped together. If it is not possible to start with equipment disconnected, you should review the steps of the lab with the equipment already connected. This will reinforce knowledge of the physical connections and device interfaces. Start with the routers, switches, hubs and cabling disconnected if possible. Your team will need to connect them according to the topology diagram in the overview at the beginning of this lab and then document you findings. This lab requires that you assemble the routers into the standard lab topology or as close as possible depending on the equipment you have. The next lab 1.5.13.2 will provide instructions for configuring the routers and workstations using Class B network address with subnets. Work in teams of 3 or more. Before beginning this lab you should review Chapter 1 in the Cisco Networking Academy Second-Year Companion Guide and Semester 3 On-line Chapter 1. The following resources will be required: 5 PC workstations (min.) with Windows operating system and HyperTerminal installed. 5 Cisco Routers (model 1600 series or 2500 series with IOS 11.2 or later) 4 Ethernet hubs (10BASE-T with 4 to 8 ports) One Ethernet switch (Cisco Catalyst 1900 or comparable). 5 serial console cables to connect workstation to router console port (with RJ-45 to DB9 converters). 3 Sets of V.35 WAN serial cables (DTE male/ DCE female) to connect from router to router. CAT5 Ethernet Cables wired straight through to connect routers and workstations to hubs and switches. AUI (DB15) to RJ-45 Ethernet transceivers (Quantity depends on the number of routers with AUI ports) to convert router AUI interfaces to 10BASE-T RJ-45 Web Site Resources: Routing basics General information on routers 2500 series routers 1600 series routers Terms and acronyms IP routing protocol IOS command summary Cisco ConfigMaker information and download Notes: Step 1 – Router Lab LAN/WAN Preliminary Planning. When setting up the lab equipment from scratch you will need to give some thought to the questions listed below. Even if you are starting with an existing assembled lab setup, you should review all steps and answer all questions to become more familiar with how the routers are connected. Even though you may not be actually connecting the equipment, you should locate, examine and document the cabling and physical connections between routers, hubs and workstations. Where should the PC's be placed? Where should the routers be placed? Where should the switch and hubs be placed? How should the Ethernet, serial and power cables be run? How many outlets and power strips will be needed? Which PC connects to which router? Which PC connects to which hub or switch? Which Router connects to which hub or switch? How should devices and cabling be labeled? Step 2 - Arrange Lab Equipment. Your arrangement of the routers and equipment will vary depending on space and physical setup of your lab area. The goal is to group each combination of router/hub/workstation closely together since they can represent separate LANs and geographical locations in the real world. It is easier to see the relationships between equipment with this arrangement. Equipment should be positioned so that all interfaces are facing the same direction and so that cabling and connections can be accessed easily. Step 3 - Connect Serial WAN Cabling. Next you will connect serial cables (DCE-DTE) between routers. With this lab setup, the router interface serial 0 (S0) is connected to the DCE cable. DCE refers to Data Circuit-Terminating Equipment (or Data Communications Equipment) connections and represents the clocking end of the synchronous WAN link. The DCE cable has a large female V.35 (34-pin) connector on one end and a DB-60 connector on the other end which attaches to the router serial interface. Interface serial 1 (S1) is connected to the DTE (Data Terminal Equipment) cable. The DTE cable has a large male V.35 connector on one end and a DB60 on the other end which attaches to the router serial interface. Cables are also labeled as DCE or DTE. Examine the cables and connections on the routers and document the connections in the table:
> From Router Name | Interface | To Router Name | Interface
> Step 4 - Connect the Router Ethernet Cabling. For routers that have an AUI (Attachment Unit Interface) Ethernet 0 (E0) or E1 port, you will need an external transceiver which converts the DB15 AUI to an RJ-45 10BASE-T connector. The 2500 series routers usually have an AUI port. The 1600 series has both AUI and RJ-45 ports and you can use the RJ-45 port without the need for the external transceiver. All Ethernet cabling from routers to hubs or switches must be Category 5 (Cat 5) and wired "straight-thru" (pin 1 to pin 1, pin2 to pin 2 etc.). Connect the Ethernet cabling as indicated in the diagram and then label the cabling at each end. Hubs should be numbered Hub 1, Hub 2, etc. Record the router Ethernet interfaces in use and which hub (or switch) they attach to in the table:
> From Router Name | Router Interface | To which Ethernet Device
> Lab-A |  |
> Lab-A |  |
> Lab-B |  |
> Lab-C |  |
> Lab-D |  |
> Lab-E |  |
> Step 5 - Connect the Workstation Ethernet Cabling. Place the PC's at their planned locations and label them (WS-1, WS-2…) from left to right according to the diagram. Run straight-through CAT 5 cables from each PC to where the switch and hubs are located. Connect the Ethernet cabling as indicated and then label the cables at each end depending on what device and interface they connect to. The following table shows the connections for all 10 workstations. Connect at least one workstation to each hub or switch. Indicated which Ethernet device each workstation connects to in the table below:
> From Workstation | To which Ethernet Device
> WS-1 |
> WS-2 |
> WS-3 |
> WS-4 |
> WS-5 |
> WS-6 |
> WS-7 |
> WS-8 |
> WS-9 |
> WS-10 |
> Step 6 - Connect the Console Workstations to Routers. Connect one end of the rollover cables from workstations 4, 6, 8, 9, and 10 to the console interface of routers Lab-A, B, C, D and E. Connect the other end of each of the rollover cables to an RJ-45-to-DB-9 serial connector. Connect the serial connector to the serial ports of the 5 workstations. Label the cables at each end. What type of cable is the console cable? Step 7 - Connect Power Cords to All Devices. Plug in and turn on all devices. Verify all of them are activated by checking their indicator lights. Are the link lights for the switch, the hubs and the Network Interface Cards (NICs) in the workstations on? Are the OK lights on the back of the routers on? Step 8 – Draw your lab diagram using ConfigMaker. Use ConfigMaker to redraw the router lab diagram to match your physical setup (routers, switches, hubs, workstations etc). This will step you though the process of hooking up all the lab equipment and specifying all IP addressing for all equipment and interfaces. ConfigMaker will also generate the actual config files which you can use for reference or to configure the router. Be sure to label all equipment (e.g. Lab-A, Lab-B etc.). A ConfigMaker introduction Lab can be found in the semester 2 labs and you can also run the tutorial if you are not familiar with the product. When you finish your ConfigMaker diagram, keep a copy in your workbook or journal. Note: If you do not have access to ConfigMaker contact your instructor or download it from the Cisco web site listed in Web Site Resources in the Overview section of this lab. You may use the space below to sketch your lab setup or for your notes.
